The episode as NWS UNR wrote it up.
A strong storm system moved across the central Rockies and the central Plains during the morning and afternoon hours, bringing snow and gusty winds to northeastern Wyoming. Rain began to fall the previous evening and then changed to snow around midnight. Snow increased in intensity during the early morning hours and continued into the afternoon. Snowfall across the area generally ranged from 4 to 8 inches, with up to 10 inches in the Bear Lodge Mountains. Gusty north winds caused considerable blowing and drifting of snow and reduced visibilities to around a quarter of a mile.
